Steps to Analyze AC
Circuits:
|
|
|
Transform the circuit to the phasor or
frequency domain. |
|
Solve the problem using circuit
techniques (nodal analysis, mesh analysis,
superposition, etc.). |
|
Transform the resulting phasor to the
time domain. |
10.2 Nodal Analysis (1)
|
|
|
Example 1 |
|
Using nodal analysis, find v1 and v2 in the
circuit of figure below. |
10.3 Mesh Analysis (1)
|
|
|
Example 2 |
|
Find Io in the following figure using mesh analysis. |
10.4 Superposition
Theorem (1)
|
|
|
|
When a circuit has sources operating at different frequencies, |
|
The separate phasor circuit for each
frequency must be solved independently, and |
|
The total response is the sum of
time-domain responses of all the individual phasor circuits. |
10.4 Superposition
Theorem (2)
|
|
|
Example 3 |
|
Calculate vo in the circuit of figure shown below using the
superposition theorem. |
